Application led November 25, 1914. Serial'No. 8f3/,872.

To all who/a t may concern:

Be it known that I, ALBERT H. DE Von, a citizen of the United States,residing at VeStield, in the county of Union and State of New Jersey,have invented certain new and useful vImprovements iii @Sewing-Machines,of which the following is a speciication, reference being-had therein tothe acconipanying` drawings.

This invention relates tov an improvement in that class of sewingmachines designed for sewing tubular articles, suclr a's the sleeves ofgarments, in such manner that the article is delivered from thework-supporting member of the machine by the action'of the feedingrmechanism as the stitchingl proceeds. The improvement has for one of itschief objects the construction of the machine` frame in such manner asto facilitate the handling of the Workand its Vdelivery to thestitch-forming mechanism under advantageous conditions. l,It has foranother object' to provide a simple and effective mechanism foroperation upon the work. i

The machine-frame is preferably constructed in general conformity withthat shown and described in my pending application Serial No. 852,345,tiled July 1914, with the work-supporting member disposedI transverselyto and laterally ,offset from the standard with which it is connected byY, means spaced above the base of the standard'.

That portion of the wOrk-supporting .nem-

ber nearest its connection with the standard is preferably contractediii girth, and may be made both of `less width and less depth than theopposite end portion provided with the feeding and stitchingineaiis,inorder to alloi7 ample slack in the material to be presented to thestitch-forming mechanism and. to accommodate the. operators fingers inmanipulating it on its way to the stitching mechanism. i y A The.-uncontracted portion of the' Worksuppoiting member is preferablyformed with reciprocally and laterally swinging sec-A tions eachsustaining a loop-taker perma-` ently connected by suitable gearing Witha driving gear upon a shaft mounted in fixed bearings of theWork-supporting member.

and itself connected through a suitable train of gearing, including anintermediate shaft, With the main-shaft journaled within a laterallyextending frame-member connecting the upper portion of the standard ofthe Work-supporting dependent connections with the said sleeve by.meaiis of which the needle-bar actuating eccentric is caused to impartoperative workadvancing and rising-and-falling movements to thefeed-dog. 'The needle-actuating eccentric preferably carries a crank-pinin its outer face fitted-Within a'n aperture of a socket memberembracing theshank of a needle-thread take-up arm mounted upon a fixedfulcrum adjacent the junction of the intermediate frame-member and theWork-l supporting member.

Journaled within aiidlongitudinally of `theinterinediate frame-meinberis a rockshaft from which is laterally extended, preferably in adirection inclined to the length of the Work-supporting member, a rigidarm carrying the presser-foot. VAsthe vibratory needle-carrying arm isdisposed above and' dog, the rock-lever and slide-bar havinginlengthwise ofthe ivxi'rk-supporting member,`

it is desirable that the operators vision be further obstructedvaslittle as possible by other yelements of` the mechanism, and by'extending `the vpressii'-f oot supporting arm at aflateral. inclinationwith the Work-supporting member and theneedle-carrying i arm, thisyelement is brought to one side of the operators range. of view of theWork which is downwardly inclined over the end member connected i'viththe intermediate frame-member. f In the accompanying drawings, Figure-lis a front elevation, With the frame in section, and Fig. 2 a sideelevation, ofa machine constructed with the present improvements. i Fig;3 is a rear elevation of the machine,

with the rearward portion of the Work-supporting member partly insection, and I iig. 4 a sectional plan vieiir of the frame standard Withthe .presser-foot lifting means. Fig. 5 is a plan of the machine. Fig. 6is a Sectional elevation of the. Work-supporting member and the partscarried thereby,Fig. 7 a plan of the lwork-supporting member, partly insection, with certain parts ,carried thereby, and Fig. 7 a detailsectionalview of an element of the loop-taker adjusting ,means FigI 8 is'a side view of the needle and feedlmeclranisms. I

As represented in the drawings, the frame comprises the hollow uprightstandard 1 having the flangedv base 2 and sustaining at its upper endthe lateral armcomprising the tubular Imember 3 tern'iinating in thedownwardly inclined` extensionl 3 connected with the top of 'thehorizontal work-supporting member 4` depending therefrom.V At thejunction of the extension'y with the member v 4 is a cavity 3 forhousing certain of'the operative-parts, this cavity being partiallyclosed by 'means fof the end-cap 5. The otherwise oval body portion ofthe standard is shown (see particularly, Figs. 1 and 4) Vflattened at 1"on the front `and inner side n the intermediate iframe member by meansof a contracted portion et', the outer uncontracie'd portion being cutaway laterallyat the upper side. to 'form at the lower side thesupportingwton ue it, above which are pivotally mounle by 'means of thevertical studn pins 6 the laterally swinging sections 7 As shown in thedrawings, ,the contracted.

portion of the "work-supporting member is both narrower and of less-depth than the uncontracted4 portion -within which thecoperate in. the.

stitch-forming elements A production of the stitching. The uncontractedportionl of the worksupporting arm is made et sufficient width and depthto accommodatethe loop-takers and. the `feed-dog with their accessories,but is'made :1s small as practicable to accommo- -date thesmal.lest-tubular 'portions of gar-` ments to be stitched. The innercontracted portion of the work-supportingmember,l ar

ranged between the un'contmcted ortion and the intermediateframe-member, 1s made suliiclently smaller than the adjacent portion topermit ample clearance for the4 finger-sof the operator in manipulatingthe fabric around the same preparatory toits presentation to thestitch-forming mecha#v 1|isin. By this means, the operator is enabled tohandle the work with ease and is not cramped by necessity of formingAthe ,garment for stitching from the outer ,face .of the fabric, whichwould be the case if the forward portion of j the Worlgfsupportingmember were uncontractedt nemers The throat-plate 8 is secured upon thetop ot the post e at one end by means of the screw 9 and upon the upperface f the member 4 at the opposite end by means. of vthe screws 10.rihe throat-plate is provided with the usual feed-dogopening 11 and`noodle-apertures adjacent ythe same.

111g operative movements to the needles and.

the feeding mechanism. Adjacent the eccentric 15 the main-shaft hasixedthereon `a bevel pinion 16 meshing with asimilar pinion 17 upon theshort intermediate shaft 18 which is in turn connected means oftheintermeshing bevel pinions '19 and .2G with the loop-taker lactuating'shaft 21 journaied within and longitudinally of the work-supportingarmand having i'ixed upon its outer extremity the driving wear 22.

lInterineshing with't e driving gear 22 are the pinions 23each 'fixedupon a short shaft 24 journaled in'bcaring bushings 25 of the respectivelaterally swinging sections 7: The stud-pinsA 6 upon which the sections'Z are fulcrumed have their axes preferably inintersecting relation withthe pitch line oi'4 Athe driving gear with the respective pinions 23 andat the rear face of the latter, so that in the swinging of suchsectionsbetween operative and retracted positions the pinions vwill beAmaintained permanently in mesh with the Fig. 7. ljlachshaft 24 hasfixed thereon a spiral gear` 2 meshing with a similargear 27 which isshown formed upon the hub of the cup-shaped loop-taker 23. Theloop-taker hub is mounted upon the'lixed horizontal ulcrum stud-screw 29tapped into the, adjustably`r sustainedholding plate 30. The

driving. gear, asv represented in late 30 is formed on its inner :tacewith an vintegral stud 31 and it carries a. second stud 32- paralleltherewith having near its outer end a flange 33 beyond which is aneccentric necked pportionli closely embraced by the vside edges of aslot extending lengthwise of j lthe plate 30, the stud 32 being held inposition by means of the'clamp-screw 35 between' whose head and theflange 34 the surroundfy ing portion ofthe plate 3()l is clamped.

The studs 31 and 32 are` slidin l t y lit-ted within suitable aperturesin thebo y y offthe 4section 7- within lwhich they are 'secured byset-screws 36 in the desired position oi'. end,

wise adjustment of thev gear tor the po sired gage of the seams. Bylooseningl the set-screws 36 and turning the stud 32 through theclamp-screw 35, the stud 32 may be shifted transversely ot' its length,thereby raising or lowering th, corresponding end of the holding plate30 and correspondingly adjusting the position of the loop-taker and itsconnected spiral gear for taking up wear or for other purposes.

The loop-takers represented in the drawings are of a well-known type,being formed with a loop-taking beak in the outer end' and having fittedwithin the same a threadcase 37 provided with a bobbin 38. As shown anddescribed more fully in my pend# ing application Serial No. 852, 345,each of the sections 7 is provided with a holding plate or" hanger 39pivoted thereto aty the lower end and provided with a lateral arm 40adapted for engagement with the hooked end 4l of a spring 42. secured ina longitudlnal channel of the pin 48 mounted within a suitabletransverse aperture of the section 7 in which it is adjustably securedby means of the set-screw 44 (Fig.

The pin has a transverse aperture entered by the reduced extremity ofthe plunger-pin 45 fitted within a suitable aperf ture of the section 7Aand resting upon the spring 42. The section 7 having been retracted as-represented in the lower part of Fig. 7, by depressing the plunger-pin45 the spring 4Q is defiected to disengage it from the hanger 39 whichmay be swung outwardly for access to the thread-cavity of theloop-taker.

Each' of the sections 7 is provided witha spring-catch 46 whose hookedoperative eX- tremity 47 is adapted for engagement .with

the shoulder of one of the latchfplates 48 secured by means of screws 49adjustably in i position upon the post 4". '".nese sections are normallyheld in operative position by engagement of the spring-catches withtheir respect-ive catch-plates, and may be vretracted for introductionand removal of the lower thread supplyto the loop-takers byy pressinginwardlyv the spring-catches for their disengagement from the shoulderedcatchplates. i

Secured upon the inner 'face of the lend? cap'5 by means of the screw 50is a fulerumstud 5l disposed vabove the work-supporting member and nearits junction with the intermediate trame-member. Momted upon the stud51`and maintained in position there.- o'n by the cap-screw 52 is the hubof the needle-carrying arm 54 provided in its outer end portion with a.socket in which is secured by means of the set-screw 55 the shank 56 ofthe needle-clamp 57 which .carries in practice two eye-pointed needles58 coperating with the loop-takers 28 in the production of stitches. l

The hub 53 isw formed with the rearwardly y extending boss 59 sustainingthe pin 60 which is slidingly fitt^d within a tangential socket oraperture of the boss 61 formed upon the lower side of the sleeve 62which is in turn fitted upon the actuating eccentric l5 ofthemain-shaft. The needle-arm 54 derives, from the described pin-andsocketconnection with the sleeve 62 embracing the actuatin-g eccentric,vibratory movements from which the needles 58 derive their sub-ystantially rectilinear reciprocations.

The hub of the needle-arm 54 has upon one side of said arm a rearwardextension 63 to which is pivotally connected one end of a link 64 whoseopposite end is sin'iilarly connected with the rearwardly extending armof'a rock-lever 65 mounted upon the fixed transverse fulcrum-pin 66 andformed with a longitudinally extending tubular member 67 disposed abovethe fulcrum-pin- Slidingly fitted within the member 67 is the tubularbar 68 constituting the shank of the feed-dog 69.

Secured by means of a set-screw 70 within l a socket in the forward endof the slide-bar 68' is one end of a flexible rod 7l whose opposite endis secured Within the rocking stud-pin 72 upon the adjustable blockl 73fitted within 'a lateral recess of the feed rocklever 74. y The lever 74ismounted upon the fulcrum-stud 75 tapped into theVcap-plate and securedin position by the jam-nut 75. The block 73 is secured for adjustmenttoward vtnd from the fulcrum 75 by means of the screw v'(6 passingthrough an elongated slot of the lever 74 and tapped into said block 73which may be adjusted by loosening the screw 76 and shifting the blockand retightening said screw. The upper arm of the lever 7 4 isformed asa slide-pin 77 which,Y is fitted within a lateral tubular boss or socket78 or" a collar 79 `embracing the shouldered crank-pin 80 which issecured in the split boss 8l of the sleeve 62.

From its described connections, the teendog receives its to-and-fro orwork-advancing movementsfrom thesleeve 62 em' bracing the commonactuating eccentric l5; while tilting movements are imparted to therock-lever 65,'and hence rising-and-alling' movements of the needles andboth Vthe worladvancing and the rising-and-falling movements of thefeed-dog are derived from the common actuating element upon the shaftl2.

Tapped into the cap-plate 5 in which itis secured by the jam-nut 82 isthe fulcrumstud 83 upon which is mounted the sleeve 84- ,r

having a split socket 8e in which is clamped l t means oi the bushingsleeve 105.

by means oi the screw vthe take-up arm 86 having the reduced andbackwardly bent portion 87 provided with the usual threado eye.Slidinglyitted upon the straight cylindrical portion of the arm 86 is asleeve 88 formed `with a lateral lug 89 apertured to receive thecrank-stud 90 which is tapped into the outer face oi theactnatingeccento tric 15.

l In the. rotation of the eccentric 15 with the shaft, the crank-studl90 is carried in a circular path and thereby communicates to the takeuparm through the described .lo connections vibratory movements upon thefulcrum-stud 83, klt will thus be seen that the reciprocation of theneedles, the operative movements of the eed-dogA and the f vibratorymovements oi' the take-up arm are 2o all derived from operativeconnections with theA actuating element 15 upon the main' shafte andthat the timing, of these several members is therefore fixed for alladjust- .dunder all operative conditions of to the mattine..

pposed to the feed-dog is'the usual presser-toot composed in the presentinstance of the preureplate 91 pivotally l connected with the lower endyof theshank 92 Whose so upper end is fitted Within the transverse boss9S of the laterally extending arm 9i lia-ving a hub 95 secured by meansofthe setserew A96 upon the rock-shaft 9? which is journaled Within andlongitudinally of,

toward the stitching position. et The roclrfshaft -9?' has secured uponits /rearward end .a collar 98 from which extends upwardly the laterallyoffset -tappet-aiin 99,

and from which depends a second arm 100;

The forwardY face ci? the tappet-arm 99 is to engaged. by one 'end oli apin `101 Whose 104 acts through the pins .102 and 4101 upon thetappet--ar1n 99 and thence thronghthe rocleshaft and lateral arm 94 tothrust the pressenfoot downward upon the work-sup- @t port, and thestress of the spring lis adapted ing across the extremityA of the member3 zo. neonato to be regulated in a manner Well-lrnovvn by The standard.1 is provided near its bese with the n spaced and apertured lugs lilo toreceive the ulcrum-pin 107 upon. which is mounted the hub 108 oi arock-lever 'trav-- y ing one arm 109 extending inwardly throngi thewallet the standard Where. it is provided with a roller-stud 110 adaptedtor engagement With one edgeo the depending' rock-shaft arm 100, asrepresented in Fig. e. An oppositely extending arm lll of saidrock-lever is formed with an eye to receive the hooked extremity 112 ofthe treadle rod 113 by means of which the rock-lever 103 109 111 may beoperated to press the arm 100 laterally and thereby rock the shait 97 inopposition to the spring 10d to liftw the presser-foot. ,In preparingthe machine for operation, the two needlethreads are led 'from thesource egt supply through. the apertured lugs 111i` of thetension-supporting' plate l115 and thence between the tension disks 116from which they are led through 'apertures 117 in a forward extensionofthe plate 115, over the guide-finger 118 and thence through the eyevof the take-np arm 86 87 from which they are led through aguide-aperture 119 in the enter end o? the needle-carrying arm 54 to`the needl ln presenting the Work ir action :be
